TALKING-MACHINE.

Specification of Letters Patent.

Patented Aug. 1, 1914.

Application filed December 4, 1912. Serial No. 734,913.

To all whom it may concern:

Be it known that I, CLINTON E. \Voons, a citizen of the United States,and a resident of Bridgeport, Fairfield county, Connecticut, haveinvented a new and useful Improvement in Talking-Machines, whichinvention is fully set forth in the following specification.

. This invention relates to a single unitary motor-plate, standardizedand interchangeable, intended primarily for use. with talk-'ing-machines that employ disk sound-records and particularly adapted foruse with talking-machines of the class known as concealed-horn orcabineted machines, although it ma likewise be employed with so-calledvisible-horn machines. However, my invention is also applicable totalking-machines that employ cylindrical soundrecords.

For convenience, I shall explain the invention with particular referenceto disk machines of the concealedhorn type where the sound-conveyerextends downward and discharges beneath the level of the turn-table.

Heretofore. in assembling such machines and installing them in theircabinets, the motor has had to be mounted in a particular position, onor beneath a shelf or other suitable support; openings must be properlyplotted and made for the main motorshaft, for the motor-controllingdevices, and particularly for the sound-passage (through the tone-arminto the horn), and particular pains are to be taken in order that allthe various mechanical parts should be brought into proper relationtoeach other and to the cabinet. In each separate installation, theseholes must be carefully located by skilled workmen; indeed, in theVill'lOllS styles and sizes of machines put out by the samen'lanufacturer, the machine devices referred to have been located in awide va ricty of different positions with respect to each other (and atdifferent distances), In short, it has been a matter of considerableskill, requiring expert labor, to install the machines properly in thecabinets; and it sometimes happens that the installation turns outunsatisfactory, and requires taking apart and re-installing, All of thishas proved very expensive, besides causing dela 111 the orn malassembling and m the test rooms. I have avoided all these diffisuchculties by producing a single unitary rigid motor-plate ortalking-machine base,a stamlardized product containing carefully locatedopenings, bearings, etc., for use in terchaugeahly with different stylesof talking-machines. By means of my invention,

standardized motor-plates can be struck up from sheet steel, the motorcan be mounted thereon in the factory, all the parts broughtautomatically into proper relation, and the whole installed in thecabinet by unskilled labor.

A preferred embodiment of my invention is illustrated in the annexeddrawings, in which- 7 Figure 1 is a plan, and Fl 2 an edge view, of apreferred niotor-p ate embodying my invention, shown as equipped with aswinging tone'arm and its sound-box and stylus.

The motor-plate 1 is of sheet steel, stamped up into substantially theconfi uration indicated, and preferably provide with 66 areconveniently-located finger-holes.

for lifting the plate with its dependent mo-r tor into or out of thetalking-machine cab-- inet.

which will protrude the upright motorshaft for carrying the turn-tableof the talk-- ing-machinc.

S is a lateral projection for presenting, at suitable distance from thecenter 7 the opening in which is secured the stationary memher 9 for theswinging tone-arm 10. At the proper distance from the extension 8 andfrom the motor is a small extension 11. hav

7 represents the central opening, through ing an opening 12, throughwhich extends the stop-and-start button 13 (shown in Fig. 2) for themotor. At 14 is a similar extension having an opening for thespeed-regulator 15 (Fig. 9). Intermediate the projcctions 11 and ll is aprojection 16 having the curved slot 17, adjacent to which is the scale18, with which co-acts the pointer 19 of the speed-ilulicutor.

20 is a conveniently-located projection for carrying a plurality ofdepressed cups 21.. for holding reserve supplies of various styles ctreproducing-necdlcs (c. (1.. hard. medium, soft and fiber). Preferably,the metal is stamped up around the margin of each cup-opening, toproduce the rims 22.

28 is still another conveniently-located projection from the plate 1, inwhich is stamped the opening for the cup 24t for used needles; suchneedles being dropped in turn through a little opening 25 in adetachable cup 26 fitted into the pressed-up flange 24 (similar to theflanges 22)..

With my new motorplate, the motor 7 (Whether a spring motor or anelectric motor) is readily secured to the-bottom of the plate 1, as bymeans of screws passing through the openings 35, as explained. Thisbrings the start-and-stop mechanism in proper positionfor control by thebutton 13, which is readily put into place and connected up; this alsobrings the speed-controlling mechanism. into position Where thespeedregulator 15 can be readily inserted through its opening inprojection 14:, and properly connected up; and likewise brings thespeedindicator 19 into proper position where it can be seen beneath theslot 17. Finally, the tone-arm is properly secured over its hole inprojection 8, which is so located as to may be omitted, or additionalprojections with openings or cups provided; and that the relativelocations of the respective projections and openings, or the distance ofeach from the center, can be varied, according to the type and size ofmotor, or the particular construction intended to be employed, withoutin any case departing from the spirit of my invention. In short, myinvention is not limited to the precise construction and arrangement ofparts, but may be varied considerably. I

Having thus described my invention, 1 claim:

1. A sheet metal motor-board for talking machines, having anapproximately circular body portion, with a centrally placed motorshaftopening therein, and two marginal projections through one of which is atonearm opening, and through the other of which there is an oblong slotor opening with a speed-indicating scale thereto.

2. A sheet metal motor-board for talking machines, having anapproximately circular body portion, with a centrally placed motorshaftopening therein, strengthening corrugations concentric with saidmotor-shaft opening, and marginal projections from said circular bodyportion having openings to accommodate the tone-arm, speed-regula torand a staftand-stop element.

In testimony whereof I have signed this specification in the presence oftwo subscribmg witnesses.
